The Tiris mangrove forest, Rhizophora apiculata-R. mucronata community, grows in the area with highly human induced stress and typically by silty clay substrate. The litterfall studies in Tiris, Indramayu (Lat. 6Âº 10-7Âº 49 S and long. 107Âº25-108Âº25 E), using litterfall trap and plot techniques indicate that the mangrove forest is very productive. Litter productivity, as measured by litter trapping of a R. apiculata dominant mangrove forest at Tiris is 1,290.95 dry g/m2 /year, and estimated as 12.90 dry t/ha/year and leaf shared is 40.70%. This is a high value when compared with the mangrove forests in the Indo-West Pacific and/or Malesian regions, and even with R. mucronata plantation in Tritih, Segara Anakan, Cilacap (Lat. 7Âº 41-7Âº 45 S and Long. 108Âº 46-109Âº E). Correlations between litter components with rainfall, number of rain-day, wind run, mean maximum temperature, mean minimum temperature, and mean monthly temperature, and relative humidity are calculated for understanding their role in litter production. These correlations are discussed and it is suggested that seasonality of mangrove need to be considered in terms of whole tree physiology rather than isolated environmental factors. Also, the high production of litter means an important contribution to support food-webs of many marine organisms. The results suggest that, in terms of litter, the mangrove forests in Tiris may be one of the most productive forest types in Java.

BIOLOGICAL STUDIES ON THE ANCHOVY, THRYSSA GAUTAMIENSIS BABU RAO (PISCES: ENGRAULIDAE) Rao, M. Babu

Publisher : Research Center for Oceanography - Indonesian Institute of Sciences (LIPI)

Biology of the anchovy, Thryssa gautamiensis BABU RAO, which forms a fishery in the Godavari estuary (East Coast of India) was studied for the three seasons, i.e. 1959-60, 1960-61 and 196162. The population pattern was studied during the three seasons by means of montly percentage length frequency curves and fitting normal curves. Length weight studies were made for the three seasons, the best fit equations to express the relationship have been calculated and differences of relationships within seasons have been tested. Relative condition (Kn) variation studies have been made for the different length groups of the fish for the two sexes. The variations of fecundity in relation to length and weight of fish respectively were studied and the equation to express their relationships have been established. The spawning season and the sizes, of ova at different stages of maturity have been determined by means of ova diameter measurement studies. The food preferences of this species have been ascertained by studying the gut contents and their item wise percentage frequencies in different months.

EIGHTEEN SEA CUCUMBER SPECIES FISHED IN KARIMUNJAWA ISLANDS, JAVA SEA Purwati, Pradina; Hartati, Retno; Widianingsih, -

Indonesia has been supplying the highest diversity of dried sea cucumbers (trepang) to world markets for decades even though species validation on the trepang from any producing areas throughout the country is still needed. Karimunjawa (Islands off north coast of Java) is one of trepang habitats. Several visits from May to November 2009 had been made to collect trepang from the fishers and collectors in that area. Eighteen aspidochirote species were identified, more varied than those reported in 1988 and 1992 although 7 species have no longer been found. Three species among those: Actinopyga banwarthi, Bohadschia subrubra, and Holothuria fuscocinerea have never been reported in Indonesia before, neither on the list of commercial sea cucumbers in Asia nor world trade provided by Choo (2008) and Toral-Grande (2007). These species composition shifts may indicate a threat to species diversity, starting with excessive removal of natural stock. Up to now, 28 species of trepang have been recognized from Karimunjawa waters.

Marine Research in Indonesia Vol 27 (1989)
Publisher : Research Center for Oceanography - Indonesian Institute of Sciences (LIPI)

Eight species of Eucheuma ait found to grow in the Indonesian waters making the amount of species of Eucheuma which had been found become 17 species. A certain species specifically found only in certain areas. Those species are usually found at the depths of 30 to 150 cm during low tide at the reef flat, moat and algal ridge of the coral reefs where temperatures and salinities varied from 29Â° to 31Â° and from 30 to 34â° respectivelly. There are various habitats of Eucheuma i.e. dead and live corals, limestones, sand and shells. Average wet weight biomass of Eucheuma species at the areas investigated varied from 2 to 552 g/m . The highest value is that of Eucheuma spinosum found in East Seram (Maluku), and the lowest is that of E. cottonii found in the Keifing Island, East Seram. The species of Eucheuma commonly found in association with Acanthopora, Gracilaria and Halimeda. ABSTRAK

SPECTROPHOTOMETRY ANALYSIS OF DEEP-SEA SEDIMENTS ALONG THE MAIN PATHYWAY OF THE INDONESIAN THROUGHFLOW: SPATIAL VIEW Nurhati, Intan Suci
Marine Research in Indonesia Vol 41, No 2 (2016)
Publisher : Research Center for Oceanography - Indonesian Institute of Sciences (LIPI)

Deep-sea sediment is the primary marine archive for reconstructing climate of the past millennia. With an array of geochemical analyses and more techniques to be developed, conservative sample usage is necessary. This study presents spectrophotometry analysis as a non-intrusive approach on deep-sea sediment samples retrieved along the main pathway of the Indonesian Throughflow in the Makassar Strait. Sediments from 25 sites including: Eastern Kalimantan, western Sulawesi, south Makassar Strait, southern Sulawesi and northern Bali are scanned as wet and dried samples over the visible spectra (400-700nm). After taking first derivatives of the raw data to accentuate the signals, R-mode factor analysis is applied to reveal three factors that explain 96.99% variance. Factor 1, which explains 53.94% variance, is characterized as halite. Factor 2 (30.89%) is carbonate and Factor 3 (12.18%) is kaolinite or clay mineral. XRD analysis reveals the presence of calcite, quartz, halite, plagioclase and aragonite, with the first three being the most prevalent minerals. Spatial distribution map of Factor 1 (halite) shows higher values in eastern Kalimantan, south Makassar Strait and western Sulawesi. Factor 2 (carbonate) is relatively high in eastern Kalimantan, southern Sulawesi and northern Bali; with similar observation at the first two sites from accompanying carbonate content analysis. Relatively high Factor 3 (kaolinite) in eastern Kalimantan is consistent with its proximity to the Mahakam River delta. Characteristics of each region are further discussed herein. Taken together, this information lays a foundation for applying the non-intrusive spectrophotometry downcore to study past climate change in the Makassar Strait.Â

SEABIRDS IN THE BANDA SEA IN FEBRUARY/MARCH 1985 Cadee, G. C.
Marine Research in Indonesia Vol 27 (1989)
Publisher : Research Center for Oceanography - Indonesian Institute of Sciences (LIPI)

Quantitative seabird data were collected in February/March 1985 in the Banda Sea. Comparison with similar data for August 1984 indicated no monsoonal influence on seabrid abundance; the median for both periods falls within the 1-5 birds per hour class.The area around the breeding island Manuk was relatively rich in both periods. Birds breeding here are "blue ocean" seabirds, foraging over large areas. Apparently, not food abundance but suitable breeding place determines their abundance here. Manuk has an enormous importance for the seabird population in the Banda Sea area, fortunately, it is a nature reserve since 1981. The breeding period on Manuk is not short and related to the NE monsoon, but extended over a larger period of the year. Manuk was known already as a breeding island in the 17th cnetury, but this knowledge was lost and only recently Manuk was "rediscovered" as such.A second relatively rich area occurred again south of Irian Jaya. Migrating birds dominated here. They probably visit this area because of relatively high food availability. Species differed for both periods. Streaked Shearwaters which breed on the northern hemisphere had in February/ March replaced the antarctic Wilsons Stormpetrel which abounded here in August 1984, but had now returned to its breeding area.

EFFECTS OF ELEVATED TEMPERATURE ON THE MORTALITY AND METABOLISM OF PACIFIC REEF CORALS Coles, Stephen L.
Marine Research in Indonesia Vol 17 (1977)
Publisher : Research Center for Oceanography - Indonesian Institute of Sciences (LIPI)

The upper thermal tolerance limits of subtropical (Hawaiian) and tropical (Enewetak) reef corals were determined both in the field and under laboratory conditions. Enewetak corals routinely withstand temperatures up to 34Â°C whereas similar exposure time at 32Â°C kill their Hawaiian congeners. These differing upper thermal limits correspond to increases of + 4 - 5Â°C above the annual water temperature maxima at each location. Reef coral temperature tolerance is therefore closely adapted to the ambient ocean temperature conditions of a geographic location.Studies of temperature effect on reef coral photosynthesis (P) and respiration (R) also showed different patterns between locations. Same species shower greater autotrophic capability at elevated temperatures in Enewetak than Hawaii. Critical temperatures estimated as coinciding with P:R ratio values minimal to support long term functional autotrophy were 2-5Â°C higher for Enewetak than Hawaiian specimens, closely corresponding to observed differences in upper thermal tolerance. Results support a hypothesis of temperature adaptation capability for reef corals and suggest that short term physiological tests can predict relative differences in temperature tolerance among coral species.

ESTUARINE MANAGEMENT AREAS: A PRIORITY RANKING SYSTEM Olsen, H. F.
Marine Research in Indonesia Vol 19 (1977)
Publisher : Research Center for Oceanography - Indonesian Institute of Sciences (LIPI)

The Queensland Fisheries Service is the instrumentality responsible for administration of fisheries matters within Queensland, Australia. The Fisheries Act provides legislation to protect, conserve, manage and develop the aquatic resources of the State. As a means of evaluating resource data a priority ranking system is proposed which provides for both quantitative and qualitative assessments of estuaries in terms of regional planning for best land use.

LIST OF MARINE ISOPODS RECORDED FROM INDONESIAN WATERS Sidabalok, Conni Margaretha
Marine Research in Indonesia Vol 38, No 1 (2013)
Publisher : Research Center for Oceanography - Indonesian Institute of Sciences (LIPI)

A list of marine isopods recorded from Indonesia has been compiled from the literature published between 1857 and 2012 as well as from Museum Zoologicum BogorienseÃ¢â¬â¢s collections and current expeditions. To date, 225 marine species from 97 genera and 19 families have been recorded from Indonesia with two parasitic families Cymothoidae and Bopyridae showing the largest number of species: 63 and 41, respectively. As for the sampling sites, waters surrounding Java, Maluku and Sulawesi have been investigated most intensively with 55, 51, and 40records, respectively. The most comprehensive publication of marine isopods in Indonesia has been that by Nierstrasz (1931). In terms of role as bioindicators, Sphaeroma and Dynamenella have been discovered to survive in polluted waters in Jakarta Bay, suggesting their potential use as bioindicators of water pollution. Future research on basic taxonomy of isopods in Indonesia as well as their ecological functions are recommended.
